AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
357 AM CST SAT FEB 22 2003

DENSE FOG A PROBLEM IN THE IMMEDIATE TERM BUT SHOULD RAPIDLY
DISSIPATE AS THE GRADIENT STRENGTHENS. INDEED THE MAGIC NUMBER
APPEARS TO BE ABOUT 10 KNOTS AS THE FOG HAS SUDDENLY LIFTED AT THE
OFFICE WHEN THE WIND REACHED 9 KNOTS. THEREFORE WILL ISSUE
HEADLINES FOR FOG EAST ALONG I80 AND ALONG THE MISSISSIPPI SOUTH OF
THE METRO AREA.

LOW CLOUDS BEHIND FRONT MAY PRODUCE AN ERRANT FLURRY OR TWO.
FORCING IS LACKING BUT ANYTHING IS POSSIBLE WITH A CI/CS DECK THAT
COULD BE A SEEDING AGENT FOR THE LOWER CLOUDS. TONIGHT QUICK SHOT
OF A RIDGE AXIS TO ALLOW CLOUDS TO CLEAR OUT LATE. NEXT SYSTEM
PROGGED TO ARRIVE LATE SUNDAY/SUNDAY NIGHT. ALL MODELS ARE EITHER A
LITTLE OR MUCH FARTHER SOUTH WITH SYSTEM THAN 24 HOURS AGO...THE
TRACK OF MOST STORMS THIS SEASON. HAVE TRIMMED BACK AREA OF PRECIP
TO SOUTH OF HIGHWAY 34 AND INDUCED A CHANCE LATE SUNDAY AFTERNOON.
AT BEST AMOUNTS WOULD BE HALF INCH...IF THAT.

COLD AIR TO SLOWLY OOZE IN TODAY AND SUNDAY WITH MUCH COLDER TEMPS
ARRIVING FOR THE WORK WEEK.

.DVN...DENSE FOG ADVISORY THROUGH 9 AM
IA...IAZ089-099.
IL...ILZ016>018-024>026-034-035.
